The numbers in list v are the totals of the triples in list t in corresponding order. I am wanting to extract from 't' only those sets of 3 that have multiple occurances in v, so I would wish to extract from t;- {{2,18,19},{3,14,22},{4,12,23},{7,8,24}, and {12,16,17},{13,14,18}}

I have tried using Select with no success, the closest I get is using Cases but with undesired results. For example
